Where orchards are thoroughly sprayed with poisons forother pests, the tent-caterpillars are usually destroj^ed at thesame time. The caterpillars of the forest species quickly drop from thetree when it is suddenly jarred, thus offering a very prac-ticable method of collecting and killing them in orchards, andespecially on village shade trees. When the apple-tree tent-. FlG. 240. Fig. 241. caterpillars and their nests or signboards are small, a wholefamily can be quickly wiped out and destroyed with an oldmitten or rag in ones hand. These nests should be lookedupon as signboards of shiftlessness, for not many injuriousinsects can be so easily controlled. Yellow-necked Apple-tree Cateipillar {Datana ininistra).—Thelarva of this moth, which usually appears in Jul}^ or August,when full grown, is from an inch and a half to two incheslong. A family of them is so voracious that if undisturbedthey will soon defoliate a small tree. Though they spin noweb, they have a peculiar habit of collecting together inmasses in the noticeable position shown in Fig. 240. At suchtimes the}^ may easily be destroj^ed by burning-, or by brush-ing them off on to the ground and killing them. The perfectinsect is shown in Fig. 241.
